Introduction
Plant operators expect pumping systems to be reliable, robust and resilient, especially in high-volume, heavy-duty chemical fluid-transfer applications. In reality, however, pumping systems are often delicate ecosystems in which system failures and breakdowns may occur, causing unexpected downtime and increased repair or replacement costs.
In today’s chemical and industrial marketplace, centrifugal-style pumps account for as much as 75% of pumps used in critical fluid-transfer applications. However, this white paper will illustrate how recent advancements in the design and operation of another type of pump technology positive displacement sliding vane can be a more efficient, reliable and safer option when transferring critical liquids in both stationary and portable systems.
While many chemical fluid-transfer operations may take place in harsh environmental conditions, the pumps and systems used to facilitate product transfer are in actuality delicate ecosystems that must be kept in balance and operate in harmony. Therefore, any upset in the system – including improper shaft alignment – can result in breakdowns that can lead to excessive downtime and high repair or replacement costs.
